What is Pigment Red 146

Pigment Red 146 (C.I. 12485) is an organic pigment belonging to the disazo pigment class. It typically produces a bluish-red to deep red shade and is widely used in industrial coloration applications such as coatings, printing inks, and plastics.

The pigment is synthesized through azo coupling reactions involving aromatic diazonium compounds and coupling components, resulting in an insoluble organic pigment with stable color properties. Compared with many traditional monoazo pigments, Pigment Red 146 generally provides improved resistance properties and broader applicability in industrial formulations.

Due to its balanced color tone and performance characteristics, Pigment Red 146 has become a commonly used red pigment in coatings, inks, and polymer coloration systems.
